JAR LIFTER.

Application filed January 11, 1921. Serial no. 436,524.

To all whom it may concern:

Be it known that I, JOHN L. KIVLAN, a citizen of United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Jar Lifters; and I do hereby declare the following to /be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to jar lifters, and more particularly to jar lifters adapted to handle jars commonly used in domestic cannin having an annular ridge near the top.

The object of the invention is to provide a simple, efiicient and economical device of the character indicated and one which, by reason of its novel construction, lends itself to co-operation with the jar to more securely hold the same.

One sheet of drawings accompanies the specification as part thereof in which like reference characters indicate like parts throughout.

F ig.- 1 is a front View of the improved device applied to a jar.

Fig. 2 is a side view of the device applied to a jar.

- Fig. 3 is a horizontal sectional view taken through the stirrup members.

Referring to the drawings, the improved jar lifter consists of a. single piece of suit.- able wire having a proper degree of rigidity and at the same time resiliency, bent into a coiled spring 1, here shown as comprising three convolutions, and then having its free parts bent downwardly as at 2- 2 to a point 3 of suitable lengths-to accommodate the hand of the user and form a handle and then bent inwardly toward each other as at 8-4 and crossing each other extending on the opposite sides a suitable distance; then bent downwardly as at points 5 into extensions 69 which are again bent into horizontal'gripping part-s 10-10 extending in parallel planes substantially perpendicular to the plane of the handle. The wire of one part is then bent upward and inwardly as at 6 and then upwardly as at 4 parallel to the part 4 and looped about the part 4 as at 7, forming a slide through which part 8 is adapted to operate.

The horizontal gripping member 10 associated with the part 8 is formed by a continuation 9 looped about member 8 as at 7.

It will be noted that the structure described constitutes two substantially parallel gripping members 10 supported by inwardly inclined members to form Substantially V-shaped stirrups, one stirrup supported by a single wire adapted to play through a space between the double wire support for the other stirrup, as clearly indicated in Fig. 2.

Normally the tension of the spring 1 is such as to hold the gripping members 10 in contact, but by pressing handle members 2 together the grips 10 are separated and adapted to 921% over and under a circu1nferential ridge a or other protuberance on a jar A.

The tension of the spring then tends to draw the gripping members inwardly against the jar, as indicated by dotted line Z in Fig. 1, and at the same time the downward weight of the iar X resolves itself in the two forces Z and Y, tending to supplement the gripping effect of the members 10 on 'the neck of the jar.

Having thus described my invention, I claim:

A jar lifter comprising a single piece of wire bent into a coiled spring and having its ends bent into substantially symmetrical crossed members, handle members intermediate said crossed members and said spring, and substantially parallel gripping members in plane's perpendicular to that of said crossed members, one of said crossed members comprising parallel spaced parts of said wire and the other of said crossed members being adapted to slide between and to be guided by said spaced members.

In testimony whereof I aflix my s1 ature.
